Hybrid zones between genetically diverged populations are widespread among animals and plants. Their dynamics usually depend on selection against admixture and dispersal of parental forms in the zone. Although indirect estimates of selection have been the target of many studies, dispersal has been neglected. In this study we carried out open field experiments to test whether males of two house ...

Arena structure caused by restricted spatial distribution of predators relative to prey 45 Restricted predator distribution in response to predation risk caused by its predators 45 Restricted predator distribution caused by limited predator mobility or habitat requirements 45 Restricted prey distribution and/or activity 47 Time allocation to safe/resting sites 47 Abstract There is a critical ne...

Ants are social insects that typically use pheromone traces to self-organize long foraging lines without any centralized organization [1]. However, a very basic question arises: how a single ant explores new territories without any chemical or " topographical " clues? To the authors knowledge, the question is unanswered in the literature. In this paper, we offer a preliminary quantification of ...

Many cognitive activities are irreducibly social, involving interaction between several different agents. We look at some examples of this in linguistic communication and games, and show how logical methods provide exact models for the relevant information flow and world change. Finally, we discuss possible connections in this arena between logico-computational approaches and experimental cogni...

In this paper we propose a hybrid physical/simulation environment for benchmarking real-time distributed control systems. This environment uses Arena® Real Time for simulation and the Java-based TINI platform for real-time control. Experimental results show that the characteristics of the physical device can be accounted for through the use of this hybrid environment. Copyright © 2005 IFAC

Background and aims Multiplayer Online Battle Arena (MOBA) games have become the most popular type of video games played worldwide, superseding the playing of Massively Multiplayer Online Role-Playing Games and First-Person Shooter games. However, empirical studies focusing on the use and abuse of MOBA games are still very limited, particularly regarding impulsivity, which is an indicator of ad...
